If Angle *theta* is 15 and Opposite Side is 10, how would you find the Hypotenuse Length?
By using 10*csc(15) since csc(15) = 1/sin or Hypotenuse/Opposite

cos θ / sin θ
Reciprocal is
The reverse of trigonometric ratios
Sine Law Needs
A side/angle pair and one side or angle

How would you prove that tan = sin / cos
Seperate the left from the right side, breakdown each trig ratio into their respective ratios (e.g y/r) and cancel out like variables and simplify
Cosine Law Formula
a^2 + b^2 - 2(a)(b)*cos(C) = c

For 3D Problems, how would you go about solving it?
Break it down into seperate triangles, determine what information you have and what information you need and then slowly solve for the variable you need
